Title: Production of 1,3-cyclohexadiene
Inventor: HINAKO HIDENORI
IPC: B01J27/198
Filed: 1994-07-06
Abstract: PURPOSE:To obtain 1,3-cyclohexadiene which is useful as a monomer for polymers, copolymers, oligomers and a curing agent for epoxy resins by gas- phase reaction of cyclohexene with nitrous oxide. CONSTITUTION:The gas-phase reaction of cyclohexene with nitrous oxide is performed, preferably over a catalyst (V0.42Sb1P0.49 on silica) at 300-700 deg.C where nitrous oxide is used in 0.1-10 molar, preferably 0.5-5 molar amount per mole of cyclohexene. In the comparison with the process where cyclohexene is allowed to react with oxygen, a large amount of diluent such as an inert gas become unneeded and the safe production operations become possible. 1,3-Cyclohexadiene is also useful as a synthetic intermediate for important organic compounds.

Abstract: PURPOSE:To dephosphorize effectively molten iron by blowing only a slag forming agent for dephosphorization into the molten iron at a specified depth from the surface of the molten iron bath through a lance with an inert gas and by adding an oxidizing agent to the surface of the bath at the same time. CONSTITUTION:A slag forming agent 7 for dephosphorization is blown into molten iron 2 in a molten iron ladle 1 at >=500mm. depth from the surface of the molten iron bath through a lance 4 with an inert gas 6 as a carrier gas. At the same time, an auxiliary slag forming agent 9 and an oxidizing agent 8 are added to the surface of the bath. The granules of the blown slag forming agent 7 diffuse in the molten iron 2 and rise to the surface of the bath while being heated. The granules become an active state and react efficiently with P2O5 formed by the reaction of the oxidizing agent 8 with phosphorus in the molten iron 2. The P2O5 is fixed in slag 3.

Abstract: PURPOSE:To simplify the decision of the presence or absence and the position of a short circuit among vertical signal lines by providing detecting switch groups on the odd and even numbered terminations of the vertical signal lines and connecting the signals of the signal lines to the control terminals of the inspection switch groups. CONSTITUTION:Inspection pulses shorter than the selecting period of the outputs of a horizontal scanning circuit 2 are inputted into the input terminals of transferring transister switch groups 3.
